"Justin is a true professional and his crew go above and beyond to complete the job. While spray foam insulation is not cheap I feel that the job I received will pay dividends years to come. Justin is deeply committed to his community and I work beside him every year as volunteers to build our ice palace before winter carnival. His ethics are shown thru this work and it translate into his business. Thank you. dave"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation FAQs, answered by experts

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

Yes, you should insulate behind shower walls. Insulating helps prevent heat loss, which keeps the shower or tub from getting too cold and helps maintain a comfortable temperature in your bathroom. Additionally, proper insulation and air sealing can help prevent wall rot and moisture buildup. It is recommended to use a high R-value rated foam insulation combined with a vapor barrier.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

While freezing pipes are less of a concern in warmer climates, pipe insulation can still be beneficial because it helps prevent condensation on cold water pipes, reducing the risk of moisture-related issues like mold growth. It also helps maintain water temperature, reducing the energy needed to heat and cool the water, which can ultimately lower your utility bills.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road.
